Crank case breather
 

I need a the round black crank case breather that goes on top of the valve cover and connects to a hose for a D24T. The previous owner broke the one that's on there so it makes a bit of a mess. I'm going to try using some plastic weld glue on the one I have to see if it holds together, but even if it works I'd still like to have a spare just in case the glue ever fails on me.

Should be easy to find in a junkyard. It is the same part that is used on all turbodiesel VWs and Audis from 1980 to 1995 (anything pre-TDI).

Oh, nice. Thanks again v8! ;)
